Windows 7 USB ports not working

[insitu]

The USB ports on one side of my HP Pavilion laptop are not working fully since recharging the battery after the power ran out and the system hibernated. (Other side is fine.) They recognize that something has been inserted and withdrawn by a sound, but will not actually recognize or power up the devices (mouse, printer, USB stick). (They work on the other side). I thought it might have something to do with disabling equipment when the power is low and disabled this function - but I have restarted many times and nothing changes. I tested the battery and it is functioning well. In control panel, all the USB devices are "functioning fully" and the drivers are up to date. Is this a hardware or software (permission) problem?????

It sounds like you've already taken several troubleshooting steps to diagnose the issue with the USB ports on one side of your HP Pavilion laptop. Since the USB ports on one side are not working fully after the system hibernated due to a low battery, we can explore further to determine if this is a hardware or software-related problem. Here are a few additional steps you can take to troubleshoot the issue:

Troubleshooting Steps:​

1. Power Cycle the Laptop:
   • Shut down your laptop completely.
   • Remove the battery (if removable) and disconnect the power adapter.
   • Press and hold the power button for about 30 seconds to drain any residual power.
   • Reinsert the battery and reconnect the power adapter.
   • Turn on the laptop and check if the USB ports are working now.
   []Check Power Management Settings:
   • Make sure that power-saving settings are not affecting the USB ports.
   • Go to Device Manager, locate the USB controllers under "Universal Serial Bus controllers," right-click on each one, go to Properties, and check the Power Management tab. Ensure that the option to allow the computer to turn off this device to save power is unchecked.
   []BIOS/UEFI Update:
   • Check if there are any BIOS/UEFI updates available for your laptop. Sometimes firmware updates can resolve hardware-related issues.
   []Reset USB Ports:
   • In Device Manager, uninstall all the USB Root Hubs and USB controllers, then restart your laptop. This will force Windows to reinstall the drivers for the USB controllers.
   []Check for System File Errors:
   • Open Command Prompt as an administrator and run the following command: sfc /scannow. This will scan for and repair any corrupted system files.
   []Test in Safe Mode:
   • Boot into Safe Mode and see if the USB ports work there. This will help determine if the issue is related to third-party software.
   []Hardware Diagnostic Test:
   • Run a hardware diagnostic test on your HP Pavilion laptop to check for any hardware issues that may be causing the problem. By going through these steps, we can narrow down whether the issue is hardware-related or if it can be resolved through software troubleshooting. If the problem persists after trying these steps, it's advisable to contact HP Support or a professional technician for further assistance.
